Difference Between Soa vs Microservices Architecture
In the following blog, we’ll come across microservice architecture benefits and soa vs microservices architecture. A distinctive method of developing software systems, Microservices or known as Microservice architecture has grown popular among the developers for creating enterprise applications. Essentially, Microservice architecture is an approach to application development in which software applications are built as a suite of independently deployable, small, modular services and each service runs a unique process as well as supports business goals through a well-defined, lightweight mechanism, often an HTTP resource API to communicate with other sets of services. Microservices is another form of SOA (Service-oriented Architecture) that structures an application as a collection of loosely coupled services, which implement business capabilities and are independently deployable by fully automated deployment machinery. The Microservice-based architecture naturally enforces a modular structure and enables the continuous delivery/deployment of large, complex applications.
Microservices vs. Monolithic architecture
There are certain differences and it’s useful to compare Microservices to the monolithic style. A monolithic application built as a single unit and any change or update requires deploying an entirely new application which requires a certain amount of preparation time, planning, potential, and money. While microservices applications, on the other hand, are independently deployable and scalable and require little of centralized management as well as enhance business capabilities with less potential and planning than monoliths.
The term “Microservices Architecture” is increasingly used in the development world. This seems to have momentum and is more for developers to create larger, more complex applications and focused on business capability. Microservices attempt to deploy independent services that work cohesively together for larger, application-wide functionality. The concept “Microservices Architecture” is more than just about technology as it reaches into the foundation of an organization and helps a business adapt to rapidly changing competitive markets. Java has a special role in building microservices as it provides a platform for building services and to embrace a common, flexible, HTTP standard based communication mechanism for mobile devices and web clients. There are three useful Java frameworks for building Microservices: Spring Boot, Dropwizard, and WildFly Swarm.
Spring Boot provides an excellent way to create stand-alone apps as well as spring-based apps with very less or zero configuration. It allows you to pick popular external tools and package them with applications. As Spring Boot applications require minimal configuration, therefore, it reduces the need for boilerplate code, annotations, and take less development time with an increase in productivity and run quickly as possible. Spring Boot is beneficial for Microservices as it simplifies deployment by packaging application with external tools as an executable jar.
WildFly Swarm, a Java EE counterpart to Spring Boot that offers an innovative approach to pick and run Java EE applications by packaging them in a JAR file. Optimized for Microservices architecture, WildFly Swarm has one advantage is that you get to select only what you need in order for the service to run.
DropWizard picks and choose altogether mature and stable Java libraries and packages them to be used for your own applications. It’s a collection of best-of-breed libraries and provides out-of-the-box support for configuration, application, logging, operational tools, and much more allowing you to build a production-quality web service in the shortest time possible. It uses Jetty for HTTP, Jackson for JSON, and Jersey for REST along with Logback, Hibernate, Metrics, Guava, Validator, Apache HttpClient, Joda Time, and Freemarker.
Examples of Microservices
Majority of the large-scale websites and applications including Amazon, Apple, eBay, PayPal, Twitter, Gilt, Netflix, Bluemix, Soundcloud, etc. have all evolved from monolithic architecture to Microservices architecture. These companies and websites dominate continuous delivery, DevOps, and are fast embracing the agile microservice framework.
Amazon is regarded as the first company to be migrated to Microservices and get API’s right before Amazon was serving on a monolithic architecture. Amazon gets countless calls from a variety of applications that can manage the web services API as well as the website itself. With the implementation of microservices, Amazon engineers deploy code every 11.7 seconds and the processes become more simplified, streamlined, and easily scalable.
Netflix, in 2009 moved to a cloud-based microservice from a monolithic architecture. Netflix with the microservices receives billions of calls every day, from different types of devices to its streaming-video API. Today, with the implementation of microservices Netflix engineers deploy code thousands of times per day.
Apple’s relation to microservices is slightly different from others. Apple developed Swift for framing iOS as well as Mac OSX applications. The further Swift code builds microservices frameworks, which gives developers a wide range of opportunity to build the variety of applications. Through Swift, it is possible to build light-weight containers, which is an integral part of a continuous deployment.
SoA vs Microservices Architecture
What is the Difference Between Soa vs Microservices Architecture?
Both SOA Service-Oriented Architecture and Microservices Architecture rely on services as the main components but vary in terms of characteristics. Soa vs Microservices Architecture is a wide subject to understand, Let’s have a look at following differences
- The typical SOA model, uses ESB (Enterprise Service Bus) for communication, with microservices uses faster messaging and less elaborating mechanisms.
- SOA built on the concept of share-as-much-as-possible” architecture approaches whereas microservices use share-as-little-as-possible architecture approach.
- SOA tends to have traditional relational database while microservices frequently uses modern, non-relational database.
- SOA focuses on component sharing, whereas MSA tries to rely minimize on sharing through “bounded context.”
- SOA is well suited for large and complex enterprise application whereas MSA is best suited for smaller and well-partitioned web-based systems.
- While developing an application MSA gives you better control. But SOA provides a better set of tools if you are trying to orchestrate a number of business processes.
- SOA can be implemented and designed in various styles. It can be a monolith or can be comprised of multiple microservices, whereas Microservices is a smaller independently deployable service.
Benefits of Microservices
Microservices, an approach to software development are small, light, modular software programs, designed to fulfill one or a few purposes. They are scalable as well as deployed independently, in small groups or in a container, designed in contrast to traditional monolithic programs to fulfill several needs. Microservices has become a common approach for the enterprise because they have several substantial benefits over their monolith predecessors:
- Easy to build and deploy: With microservices developers can easily build large and complex applications. As larger applications have many different modules, that requires being integrated and deployed. Microservices architecture allows users to load the required services resulting in improving deploy times.
- Flexible: Developers can make any changes easily without affecting other services.
- Easily scalable: Compared to the monolith’s one, a microservices application can be easily scalable up and down and can be integrated with third-party services.
- Easy to understand: Easy to understand and modify thus they can help a new team member become productive quickly.
- Microservices embraces easy integration and automatic deployment, using open-source continuous integration tools such as Jenkins, etc.
